UNITED STATES PATENT OFFICE.

HENRY H. MERCER, 0F CLAREMONT, NEW HAMPSHIRE, ASSIGNOR TO SULLIVAN MACHINERY COMPANY, A CORPORATION OF MASSACHUSETTS.

STONEWORKING MACHINES.

Application filed September 28, 1918.

To all whom t may concern.'

Be it known that I, HENRY I-I. MERCER, a. citizen of the United States, residing at Claremont, in the county of Sullivan and State of New. Hampshire, have invented certain new and useful Improvements in Stoneworking Machines, of which the following is a full, clear, and exact specification.

This invention relates tostone working machines, and more particularly to machines Vof the channeling type, the object of the present invention being to provide a simple but ei'iicient apparatus mounted on the channeler truck, and intended more particularly, though not exclusively, for the purpose ot cutting the corner oi' a channel groove which extends under an overlying side wall or roof of a quarry, or for cutting under any other conditions to which its particular construction is suited. A. more specific object of the invent-ion is to provide a simple mechanism for swinging the standard 4carrying the tools from a vert-ical position to an inclined position, to provide means for securing the standard in a vertical or in an inclined adjusted position, and to so mount the standard swinging mechanism on the channeler truck that the tools will make a continuous swinging cut as the channeler is fed under the roof or hanging wall.

The invention will be best understood by reference to the following description, when taken in connection with the accompanying illustration, of a speciic embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings,-

Fig. l is a front elevation of a channeling machine embodying one form of the invention.

IFig. 2 is a plan view of the guide and bar.

Fig. 3 is a view on a smaller scale, showing the channeler in a different position when used for corner cutting'.

F ig. 4 is `a sectional View taken on line 4 4 of Fig. l, the rotating parts being shown. in elevation.

Referring yto the drawings and to the machine shown therein, while the invention Serial No. 256,056.

may be embodied in machines and devices other than the specific type herein shown, for the sake of illustration there is shown one embodiment of the invention in a track channeler of a general type extensively used, the same comprising suitable channeling mechanism mounted on the usual trunnion bar l, carried by -a cross frame member 40 rigidly connected to journals 4l, by means of which the truck body is mounted on axles carrying wheels 2, the latter being adapted to travel along a trackway 3 cus` tomarily laid on the quarry bottom. In accordance with the present invention, holes are bored in the web of the track rails for securing a rack 5 at different places along the rails, it being understood that this rack may be dispensed with where the track is built with rails having a rack formed thereon.

The channeling mechanism, which may be mounted on either end of the trunnion bar, comprises a standard G usually retained in adjust-ed position by one or more inclined braces. The standard is provided with suitable vertical guides 7 in which is mounted a sliding frame 8 carrying the cutting mechanism, said sliding frame being vertically adjustable in said guides to move the cutting mechanism toward and away from the work by means of suitable feeding mechanism which forms no portion ofthe present invention and which, being of usual construction, is not illustrated herein. rfhe sliding frame is provided with vertical guides 9 in which is slida-bly mounted a crosshead l0 carrying a gang of channeling tools ll.

The cross head and tools are reciprocated through suitable connections from a crank shaft l2 actuated by the usual motor, not shown. The connections between the crank shaft and crosshead are such as to provide an elastic yielding medium between said parts, and to convert the rotary motion of the crank shaft into a movement of the tools which will cause them to perform their functions in the most eiiicient manner. As herein shown, the crosshead is connected .to a piston rod 13 secured to a piston, not shown, working in a cylinder 14: which is reciprocated in the sliding frame by a pitman 19 connecting it with the crank shaft 12, the frame for that purpose having secured thereto guides 15 which receive suitable slides 16 carried by the cylinder 14. A suitable guard plate 17, having an opening 18 to facilitate the inspection and oiling of the connection between the pit/man 19 and crank pin, is fastened to the standard.

rllhere is usually employed in machines of this type, an inclined brace, attached at its upper end to the top of the standard, as at 20, and secured at its lover end to the trunnion bar, to retain the standard in a vertical position. In substitution for this usual brace, the present invention contemplates the provision of a mechanism which will hold the standard in a vertical or inclined position or will swing the standard on a bearing, shown in dotted lines at 1, carried by the trunnion support, as the truck is moved back and forth during the cutting operation. This mechanism comprises a double ended bracket or support 21, having clamping means 22 and 22 controlled by bolts 23, by which it is held to the trunnion bar l, the clamping means being disposed at an angle to each other sothat either one or the other' of the clamps may be. bolted near one or the other end of the frame to hold a channeled guide and supporting member 241 at the required angle to the frame. The clamps 22 and 22 are rigidly connected with the guides 24 by webs 25, and with each other by a web 25', as is shown in Figs. 1 and l.

Sliding` in and supported by the guide 24 is a b-ar 26 on the lower side of which are cast shrouded teeth 27, and on the upper side of which is a lug 28. The guide 24 is provided with a longitudinal slot 29 in which the lug moves when the bar is given a reciprocating motion. A tie rod or brace 30 is connected by a bolt to the standard at 2() and by a yoke 31 and bolt 32 to the lug 28. The guide is split at both ends, as shown at 33, so that the sides of the guide may be pressed toward each other to serve as a clamp to hold the bar 26 in different positions. Bolts 34 are provided for operating these clamps, the bolts passing through holes formed in lugs on the under side of the guide. Nuts are threaded onto the ends of the bolts and may be tightened to give the necessary frictional engagement between the sides of the guide and the bar.

A driving pinion or cog wheel 35 is carried by one of the wheels 2 and is detachably held thereon by suitable means, as by bolts 36. Meshing with the cogs on the driving wheel 35, and also with the cogs 27 on the bar 26, is a cog wheel 37 held by a Cotter pin 38 on a stud 39 carried by the web 25.

When the channeling machine is being used in a vertical or adjusted position, the upper clamping means 33, 34 on the guide is adjusted to grip the bar and thus make a rigid brace extending from the frame to the top of the standard. During this operation, the rack 5 or driving wheel 35 is removed, so that there is nov driving connection between the rails and the bar. If it is desirable to break the driving connection for but a short time, the rack and driving gear are kept in place and the driving gear 37 is removed by pulling the cotter pin 38 and sliding the gear 37 oif the stud 39. When it is necessary to make a cut under an overhanging wall or roof, as illustrated in Fig. 3, a driving connection is made from the fixed rack 5 through the driving and driven gears 35, 37 to the bar 26. Vhen the truck is moved to the left, the bar 26 is forced to the right, so that the standard is swung about the axis of the pivot 1 in a plane eX- l tending longitudinally of the truck, carrying the tools 11 forwardly ahead of the truck, and when the truck is moved to the right the standard is returned to an upright position.

If it is desired to tilt the standard backwardly transversely of the truck, as is found necessary in certain rock formations, the clamping bolts 23 are loosened, the standard is tilted on the trunnion bar 1 in the usual manner, and the bolts 23 are again tightened to hold the swinging mechanism in an inclined position. To allow fo-r this relative movement of the gears, the teeth are so cut i as topermit quite a little play between them, and the distance between the centers of rotation of the gears is made greater than `is usual with gears of this type.

It will be observed that, by my improved channeler swinging mechanism, I have provided a simple, strong, and efficient means for swinging a channeler standard on its trunnion supportat any angle to the truck frame, that the moving parts are carried entirely by the frame, that readily accessible and easily operable means are provided for throwing the swinging means out of action, and that when the swinging means is inoperative to swing the channeler it may be used as a brace to hold the standard in any desired position.

VWhile there is herein shown and described for purposes of illustration one specific embodiment of my invention, it is to be understood that the latter is not limited to the details of construction herein shown, nor to the application of the invention herein illustrated, nor to the specific form of machine to which the same is shown as applied, but that extensive deviations may be made therefrom without departing fro-m the spirit of the invention.
